Description
As a certified reference material (CRM), 3,7-Dichloro-6-methoxy-1-benzothiophene-2-carbonyl chloride meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
CATO supplies 3,7-Dichloro-6-methoxy-1-benzothiophene-2-carbonyl chloride (CAS 34576-80-2), a certified reference material (molecular formula C10H5Cl3O2S, MW 295.57 g/mol) for analytical method development and quality control.
Structurally, 3,7-Dichloro-6-methoxy-1-benzothiophene-2-carbonyl chloride (C10H5Cl3O2S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 295.57 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
